A researcher found a study relating the value of a car, y, to the age of the car, x. When researchers looked at the association of x and y, they found that the coefficient of determination was r = 0.158. Select two conclusions that the researcher can make from this data. [ a.) The correlation coefficient, r, is 0.397. b.) About 16% of the variation in value of the car is explained by a linear relationship with the age of the car. 0 c.) The correlation coefficient, r, is 0.025. d.) About 84% of the variation in the 0 value of the car is explained by a linear relationship with the age of the car
